Battery chargers:
High-performance solutions for industry and transport

MSB offers a range of robust, powerful battery chargers, AC-DC switching power supplies and rectifiers in unidirectional and bidirectional designs. The use of bidirectional DC- DC converters makes sense in order to generate an “emergency power supply”, e.g. for emergency ventilation, in the event of a power failure.

Our AC-DC switching power supplies use a high-frequency power conversion topology and optimized magnetic fields to ensure reliability, efficiency and compact dimensions.
For charging batteries without galvanic isolation up to 900 Vdc, the use of bidirectional DC / DC and AC / DC converters for battery charging and for generating emergency power networks is an inexpensive option.
